A bomb injured three people outside an anti-terrorism court and government offices in the southwestern Pakistani city of Quetta on Thursday, police said.
The device was planted in a bicycle stand outside the office of the local district coordination officer, where an anti-terrorism court is also situated, they said.
"The blast occurred after an unidentified man parked his bicycle in the stand outside DCO office and three people were injured," senior police official Raja Ishtiaq told AFP.
"It could be a locally-made bomb fixed under the seat of the bicycle,"
Baluchistan province, of which Quetta is capital, has been in the grip of a three-year rebellion waged by ethnic Baluch rebels seeking more political rights and a greater share of profits from the region's natural resources.
Hundreds of people have died in violence in the province since the insurgency flared in late 2004.
The province bordering Afghanistan has also been hit by attacks blamed on Islamist militants. (AFP)
